Allow java format to not wrap stream calls

[quim3ra]

I really love the plugin, but I think it's need a little bit of configuration to avoid wrapping every chained call, for streams is a nightmare, it's not the same reading this code block:

Stream.ofNullable(shops.getShops())
            .flatMap(Collection::stream)
	    .map(converter::convert)
	    .collect(Collectors.toList());

Than this one, after the java format has been executed:

Stream.ofNullable(shops.getShops()).flatMap(Collection::stream)
	    .map(converter::convert).collect(Collectors.toList());
